Built-in functions : order function

order function (new in v6.9)

Takes an array of numeric values and returns an array containing the indices of those values in ascending order.

Example:

order([1,9,2,10,3,8,5]) -> [1,3,5,7,6,2,4]

Note that the result of order() can be used to get the original values in ascending order by using it in the element function. e.g.,

mixed = [1,9,2,10,3,8,5]

sort = order(mixed)

element([mixed],[sort]) -> [1,2,3,5,8,9,10]
